Let me explain you. It is unlikely that India and China go for a full flagged war. The conflict between India and china is most likely in border area to establish control over territory where there is dispute of ownership. In this kind of small conflict, how are you going to stablish your dominance rapidly is the key to success. By the time some ceasefire happens, if your dominance is there, you will be in a better position to negotiate. Indo china conflict in 1962 is an example which went against us. While our swift and decisive response in 1967 gave us control over Chola and Nathula.
Imagine a Doklam like situation where both army goes for conflict. If we hit Chinese hard and get control over the area than we can enjoy the possession. If we lose control, it will go china. This is the reason we require highly specific weapons which may give us an initial edge in conflict. We need to prepare for this. Infact, this sort of small conflict like it happened with Pakistan is going to happen in near future.This is the reason why conflict specific weapons are going to be very important. You will see highly sophisticated sniper rifles, machine guns, short range missiles, drones, artilary guns being purchased in large number than big weapons like tank etc in priority.
